Full-Stack Engineer (Kotlin & React) – Contractor

Remote, Bulgaria

Full-Stack Engineer – Contractor

Our client builds self-organizing technical teams and provides end-to-end software development services for partners worldwide. With more than 300 successful projects—including long-term collaborations spanning over eight years—they focus on sustainable delivery and long-term value.

Operating as a cooperative, the organization practices self-management and empowers individuals to influence direction and strategy. Team members have the opportunity to become co-owners and share in the benefits of collective success.

We are looking for an experienced Full-Stack Engineer to join a high-impact product team focused on transforming how banks and card issuers manage risk. By leveraging automation, their platform streamlines fraud-related workflows and card dispute processes—helping financial institutions reduce inefficiencies, minimize losses, and strengthen customer trust.

What You’ll Be Working On

You will contribute to a platform that enhances risk and fraud operations in the financial sector. The tech stack includes:

Frontend: TypeScript, React, Redux
Backend: Kotlin, Spring, PostgreSQL
Infrastructure: AWS
Productivity: AI-assisted development tools (e.g., Cursor), applied thoughtfully and responsibly

You will play a key role in designing and building scalable backend services, and—if you are full-stack—implementing frontend features that integrate seamlessly into the product.

Your Role

As a Full-Stack Engineer, you will:

Design, build, and maintain backend services and APIs
Contribute to frontend development for full-stack responsibilities
Participate actively in architecture discussions and technical decision-making
Own tasks end-to-end—from planning and development to deployment
Collaborate closely with a small, agile team and communicate proactively
Help ensure high code quality, reliability, and system scalability

This role requires both technical depth and the ability to work autonomously in a fast-moving environment.

What We’re Looking For

We seek engineers with an ownership mindset—people who take initiative, uphold high standards, and consistently deliver reliable results. You should feel comfortable contributing across the stack, collaborating proactively, and communicating clearly in a distributed, agile environment.
